Rebuilding the xr650r to have stock compression, HRC camshaft and chain, and ported and polished head with all new valves. The ultimate combination for reliability and power, tried and true by Johnny Campbell himself.
I am about to embark into something similar and your tutorial is mind blowing. Will you be able to answer me if I need some inputs along the way, which I think I will? I am mechanically inclined but not gifted like you are. I've enjoyed every second of your explanation. That video is dummy proof. with much love and appreciation from Haiti 🇭🇹.
For the lads without manual, the torques for the 6mm bolt is 9 footpounds (21Nm) as the man said, but the 8mm ones are 17 footp (not 13.) (23Nm). thanks for the vid! Cheers
Have you had any issues with the bike since you rebuilt it? This video was really helpful, but it looks like you used the whole tube of gasket maker. I wouldn't be surprised seeing the oil galleries get blocked up or cam bearing seize from all of it getting pushed in there
Hey friend. Got er running and idling fine. But getting a lot of smoke coming from the headers, not out the actual exhaust pipe though.... Could that be break in oil burning off or something else?
Ok so you set cam in lobes down cam gear markings level with head and correct and chain on,and piston is at top dead centre how do you know its on the compression stroke? or does it not matter? also notice you donot have your cam tensioner in yet will it push timing out when installed and puts pressure on the cam chain? cheers
im haveing problems with my compression realise i think when i tryed to set the valve the right side seam to be to tite and left side is good when i kick it over by hand there like a clicking sound in the head after it turns the motor over at least 3 times then the right side gets lose is that normal?? or sould i put the head
i notice on your you dont have those 2 tubes that are next to exshast did you block yours off im new to the xr650r and trying to find out how stuff works and tech stuff to make it better
Practice. I've acquired the ability to keep tension on the sprocket with just my hand whilst observing the timing marks. I then keep the same tension when bolting on the cam.
Fair enough :) I've always struggled a bit getting the top sprocket/chain timed right with the crank. Just wondering if you had some special method. Looking at tearing down my xr this winter so am just prepping myself watching some vids. This video is extremely handy... Thanks for making it!
@@desertspeed2934 :). I'm just being a d!ck. It just looked like she purposely wanted to loiter in the general direction the camera was pointed. No harm meant.

Thanks a lot for this video. I dont have a manual yet and this is saving my ass big time. Cheers from Alberta
Wow , thank a lot! It help me a lot.

sorry 9 ftpound is 12Nm (dislexia of mine ;)
Awesome info...thanks
wow, you are genious. Impressive skills.

Nope. Gasket maker is anti spread. Also if you leave it alone and let it dry it won't spread or get in the way.
Hey friend. Big thanks for the video!
Any chance you could go over the piston ring configuration again or link the said video ?
If exhaust is 0 and intake is 180 degrees, top compression is 180, second compression is 0, both scrapers are 90, and oil spacer is 180.
@@desertspeed2934 ok
Thank you for the reply
Im pretty sure I got it right

Doesn't matter
@@desertspeed2934 ok thanks
Hi is that a standard cam with the auto decom removed or is it a stage 1 or stage 2 thanks.
Standard w/o decomp&anti-kick
Hey do you need to take out the auto decompressor plunger for a hotcams?
No you do not.
@@desertspeed2934 any advantage to taking it out, looks like yours was out?
zip ties make good ring compressors
Oh man! I haven't had a good laugh like that in a long time! :'D

i notice on your you dont have those 2 tubes that are next to exshast did you block yours off im new to the xr650r and trying to find out how stuff works and tech stuff to make it better
No, I bought a blank head and had it machined and milled out without the smog pump ports by precision concepts.
That sounds like a stretched can chain jumping teeth or a tight compression release cable.
i also notice that you dont have the automatic compresor release on your cam does this make it harder to start as in harder to kick start
No, easier to start and more power.
how did you time the top sprocket without it on the shaft and tensioned up?
Practice. I've acquired the ability to keep tension on the sprocket with just my hand whilst observing the timing marks. I then keep the same tension when bolting on the cam.
Fair enough :)

You assumeing next time use torque wrench
What??
Your girl looks jealous that you're paying more attention to your bike than her.
Actually tge camera man's GF, not mine.
